我無法動態綁定背景,因爲它會引發異常「A'DynamicResourceExtension'不能在'Binding'類型的'Source'屬性上設置。'DynamicResourceExtension'只能在DependencyObject的DependencyProperty上設置。如何動態綁定WPF中的背景顏色?

<Window.Resources>
<SolidColorBrush Color="Blue" x:Key="customColorBrush"/>
</Window.Resources>
<Grid>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<Button Background="{Binding Source={DynamicResource customColorBrush}}" Margin="20"></Button>
<Button Background="{Binding Source={StaticResource customColorBrush}}" Margin="20" Grid.Row="1" Click="Button_Click"></Button>
</Grid>
您應該更好地使用MVVM結構的綁定 – Ugur
